"I told you: I am a goddess and princess. There are no other valid descriptors... though I suppose a demonstration of my tricks is in order, then?" Natsumi asked, face breaking into a terrifying grin. She was the more sane sister indeed... but a perusal of the full stock of her abilities indicated that she couldn't be entirely stable. Few people would willingly chip away at their own life in order to gain a few new tricks.
The goddess snapped shut her fans... and disappeared, reappearing upon the other side of the pool, perched exactly on its edge. A slight shift in how she held herself followed; three whirling rings of fiery script sparked into existence around her, spinning to an unheard rhythm and accompanied by a thunderous proclamation: "Fate--Old Immortal Fire!"
Apparently not content to stop there, one of the goddess's hands went to her throat, whilst the other pointed itself at the ceiling: "Brilliant Dragon Bullet!"
The white cone this created was almost blinding in its intensity; though it strangely didn't harm the ceiling. Any tiny vermin clinging to it were doubtless toasted, however, with the dragonbreath--not fire, but something close--burning across them.
